Description
SKF LGHB 2 is a high-viscosity grease based on mineral oil and calcium sulfonate complex. It withstands high temperatures and extreme loads and is suitable for a wide range of applications, particularly in the cement, mining, and metallurgy industries. This grease is additive-free. Its extreme-pressure properties are due to its soap structure.
Technical characteristics and advantages
- Excellent load-bearing capacity, protection against oxidation and corrosion even when exposed to large amounts of water
- Withstands peak temperatures of 200°C (390°F)
Application areas
- Plain bearings with steel/steel contact surfaces
- Machines in pulp and paper mills
- Vibrating screens
- Continuous casting machines
- Sealed spherical roller bearings operating at temperatures up to 150°C (300°F)
- Bearings for work rolls in steel production
- Forklift boom rollers
